Abu Hurairah narrated that the Messenger of Allah (s.a.w) said:
"When Allah created Paradise and the Fire, He sent Jibril to Paradise , saying: 'Look at it and at what I have prepared in it for its inhabitants.'" He (s.a.w) said: "So he came to it and looked at it, and at what Allah had prepared in it. He (Jibril) said: 'Indeed, by your Might, none shall hear of it except that he shall enter it.' Then He gave the order for it to be surrounded with hardships. He said: 'Return to it and look at it, and at what I have prepared in it for its inhabitants.'" He (s.a.w) said: "So he returned to it and found it surrounded with hardships. He returned to Him and said: 'Indeed, by your Might, I fear that none shall enter it.' He (s.a.w) said: 'Go to the Fire and look at it and at what I have prepared in it for its inhabitants.' So he found it, one part of it riding the other. So he returned to Him and said: 'Indeed, by your Might, none shall hear of it and then enter it.' So He gave the order for it to be surrounded with desires, then He said: 'Return to it.,' so he (Jibril) returned to it, then he said: 'Indeed, by Your Might, I fear that none shall be saved from it except that he shall enter it.'"
